Reading the r.profile man page, you will see that it's possible to pipe 
the list of coordinates to r.profile:

The *profile* parameter can be set to comma separated geographic 
coordinates for profile line endpoints. The interactive flag (*-i*) 
overrides this option. Alternatively the coordinate pairs can be piped 
from stdin, one comma separated pair per line.

You can get the coordinate pairs from your track vector with 
v.out.ascii, and use the fs=, option to make the output file 
"comma-separated".
